模拟量输入端子模块 el3142 用于给现场测量传感器供电，并以电气隔离的方式将模拟量测量信号传输给自动化设备。 端子模块通过电源触点为传感器供电。

The job of the EL3142 analog input terminal is to supply power to measuring transducers located in the field, and to transmit analog measurement signals with electrical isolation to the automation device. The voltage for the sensors is supplied to the terminals via the power contacts.

一、使用EL3142测量电流信号，发现测到的信号抖动严重，不能稳定，而同样的信号用EL3042测量则不抖动，原因是什么？如何解决？ 通过检查两者的参数发现，除了Resolution不同外，另一个不同点在于信号转换时间的不同，如下：

EL3142. Analog inputs. 2. Signal current. 0 mA…20 mA. Internal resistance. 85 Ω type. + diode voltage. Resolution. 16 bit (including sign) Sampling type. simultaneous. Ground reference. single-ended. Conversion time (default setting: 50 Hz filter) approx. 60 µs (Fast-Mode: ca. 40 µs)
